Today we revisit the topic of island biogeography to learn about some more isolated environments, each with their own collection of unique animals as a result.

Inch? How much is one inch in cm?
Atlas Pro coming in hot with the best videos. Have you considered doing a video about the rift and how plate tectonics are splitting Africa? Sounds interesting and wanted to see your take on it!
You should rename your channel to Island Pro
please make a video about the origin of wind how did the first gust happen and is it still happening
There's also been giant lake trout in Lake Superior at Stannard Rock being under a similar situation to the plateau. Just with Stannard Rock a lake mount being a source of food being far enough away with minimal to no human predation pressure due to Stannard Rock being extremely isolated and dangerous to travel for fishermen.
Edit: In other words, species diversion is probably occurring with these island gigantism cases of trout over time because humans isolated these trout with adequate food and lack of predation (as there's few safe days to fish there) while places closer to shore get human fishing activity.
You should talk about paramos at some point! Fascinating thundra environments right in the tropics
I would love to see a video on the many lakes in Canada and what sort of species diversity can be found among them!
The fact that this assimilation is specifically focused on the youth of Starfleet really had me feeling uncomfortable, especially with the indoctrination narrative surrounding queer folks and feeding into the somewhat ageist attitude that young people as a collective are trying to ruin society by drawing attention to systemic issues and not doing things like their parents; you know Millennials / GenZ are ruining society think pieces.
Taking control of the youth and turning into a malevolent force honestly embodies that conservative fear, especially highlighting queer people.
So Olympic National Park has 3 distinctly different biogeographic regions that you would consider islands? Take a look at the park and tell me what you think. There is Hurricane Ridge, Temperate Rainforest and Pacific Coastal regions in the park on the same peninsula.
When you say caves are challenging for all life because there's not enough time for evolution to occur. What about microorganisms which have much faster generational turnover? Doesn't this mean there are whole kingdoms of life that could include species that might be endemic to caves specifically?
The town I live in is literally called island in Italian, yet isn't even an island anymore, and hasn't been for over a century
I'm curious about animals inhabiting our cities like subway rats and pidgins. While not old enough for species to evolve, do cities have animals that have gone extinct elsewhere thus trapping them like an island?
Please stop showing your face
I remember learning as a kid that the island of Oahu had many different species of snails that all evolved from 1 species that were all endemic to their own small part of the forest, many that were endemic to 1 specific tree.
I love this series, keep it up!
11:20 *Dobličica
And the wrong river is highlighted. Seems like you highlihted Kolpa.
My favorite fact about seamounts is that they are described via "summit depth".

Are there any interesting examples of adaptations in extreme alpine environments? You have the best channel btw
This make that hook of medieval adventures to get a flower that only grows on the top of the mountain much more beleivable
The Olm, the Gollum of Salamanders
I love the physical map of the ex YU region since my heritage is from there. If you go a bit further south you will find Lake Ohrid. It is the oldest, deepest and highest large lake in Europe. It's also the only large lake that is fed by underground streams and the only lake that has a river that runs out of it instead of into it. It also has 200/300 endemic species. Over the mountains, right next to it is Lake Prespa, another large mountain lake. It has an island called 'Golem Grad' or 'Snake Island', because it's full of endemic snakes! How they ended up on an island on a lake? IDK. Anyway, great video.
Would all the Ohms be connected by underground rivers that are part of the Black sea watershed while their main habitats are clearly in the region of the Adriatic watershed? anyone?
Personally, I'd love to see something like the Madagascar section of your video but for the Appalachian Mountain range. As an example, the worlds smallest tarantula species lives on the top of Grandfather Mountain. Its called the Spruce Fir Moss Spider and only lives in Spruce Fir Moss!!
Anyone else now have a dying need for a B. Nana as a pet? They are almost a cute as (and I’m as likely to get one) as a Canadian House Hippo…
Not 1..3..prove evolution..queers talking or cartoons or cgi is not proof.
18:27 I actually know the answer to this and you were close but slightly wrong. The fossil record shows that Chameleons actually evolved in Madagascar and the went to mainland Africa from Madagascar not the other way around.
One of my favourite examples of cave life has to be the Movile cave in Romania, Which I believe is/was completely separated from the outside world, Yet still has its own ecosystem, Relying on chemosynthesis rather than energy brought in from outside the cave, Making it actually in some ways similar to the Hydrothermal Vents at the bottom of the ocean (Which are another quite fascinating island analogue, Actually.), As it's one of the few places on the planet where life thrives without any reliance on photosynthesis.
What about non-islands that are islands.
Wow over 1,000,000 followers. I remember when I joined you were around the 200k mark. Love every single video you make ❤
pattern recognition is the most critical trait of the home sapiens, understanding of the fact that 'island isolationv' is a limiting term is a huge thing
Can't wait for Atlas Premium
Very informative video ❤
We call it isn'tland
Wait until he figures out Earth is an island in space….
very hard to hear your voice over the netflix normalization compression.
Doblicica stream on the map is in Croatia, not Slovenia
4:30 I'm surprised you didn't mention (early) human as an animal seeking shelter in caves
Such infotainment is why YouTube is still the king 👑
